Abstract

一种充电***，包括：电池包(25)和充电器。该充电器包括：电源电路(21)和充电电路(22)；电池包(25)包括储能单元；该充电***还包括充电器内的第一电子开关(23)和电池包(25)内的第二电子开关(24)；充电***进一步包括监测电路(26)，监测电池包(25)、充电电路(22)、电源电路(21)的状态；以及控制电路(27)，可根据监测电路(26)的监测结果控制充电***的工作状态；当监测电路(26)监测到预设状态发生时，控制电路(27)控制充电***执行以下动作中的至少两个：1)关断第一电子开关(23)；2)关断第二电子开关(24)；3)降低或关断电源电路(21)的直流电源输出。该方案的有益效果是通过执行两处关断动作保障在需要关停充电进程时不论电子开关是否失效都能有效防止充电异常的产生或恶化。
